Application filed January 14, 1905. sicrial No. 241,182.

' said telly comprising two continuous circular rigid members adapted totit one against or above the other and forming by the superposition oftheir respective grooves an annular closed housing in which is inserteda continuous spring-ring, the ends of which are attached to twoconnecting-links pivoted to a common exteriorly-projecting tightening orloosening device, so that said ends can instantaneously be loroughttoward or moved away fromeach other when said tightening orlooscningdevice is manipulated from the exterior,.

thus .causing the spring-ring in the housing to assume either itssmaller diameter, in which dismounting of the rim maybe easily effected,or its larger diameter, in which the two members of the rim are stronglyconnected together.

in the accompanying drawings, Figures 1 to 5 represent one form ofconstruction, in which the spring situated within the housing in thefelly tends to close itself by reason of its elasticity. Fig. 1 is asectional elevation of a portion of the telly in its active or oper-.lblVG position.

Fig. 2 is a partial longitudinal section of the sprir1g-ring, showingthe pivotal connection thereof. Figs. 3 is cross-section of the telly onthe line A A of Fig. I. Fig. 4 is a sectional elevation similar to Fig.1, but showing the spring in its inoperative or dismounted position.Fig. 5 is a section on the line B B of Fig. 1. Figs. 6 and 7 represent asecond form of construction, in which the spring situated in the housingof thefelly tends to force itself open. Fig. 6 is a sectional sideelevation showing the spring andits connecting links in full lines inthe operative position and in broken lines in the dismounted position.Fig. 7 is a cross-section on the line C C of Fig. 6, the movable devicebeing shown in the dismounted position. Fig. 8 represents aslightmodification of the form of the folly or rim.

Referring to Figs; 1 to 5, it will be seen that the telly comprises tworigid metal members a and Z), fitted one above theother. Each member isshaped to formon one side an annular or circumferentialgroove, so thatwhen they are fitted together a closed housing is pro duced into whichis inserted a non-continuous ring or steel spring al, the ends of whichare provided with two connecting-links f and g, pivoted on a common pinor axle 7:, upon which is also pivoted a pulling or pushing member orbutton 5, which projects outwardly through an aperture fin the bottom ofthe housing 0. In

the position of rest the spring, which tends to coil or close itself, isin the position shown in Fig. eL-that is to say, is completely lodged inthe groove of the member a, so thatin this po sition the second memberZ1 can be easily removed or fitted by sliding it on the member a. Whensaid two members are to be strongly connected for use of the wheel, atkey or lever is used having two cylindrical tenons ate certain distancefrom each other. One of the tenons is inserted into a hole 0 in a fixedpart of the felly and the second tenon into a holep in the button c. Thekey is then manipulated so that it pivots round the center 0 and pushesthe member toward the interior of the housing 0, thus extending thelinks f and g and expanding the spring. If this movement is continued soas to completely straighten out the links fand 1 the spring bearsagainst the upper wall of the housing 0 and holds the connecting-linksrigidly in the position shown in Fig. 1. the groove in the member] andpartially engages the groove in the other member a in such a manner thatsaid two members are strongly connected together. Should one of thepivot-pins of the connecting-links break, the shape ofthe parts wouldprevent thespring from closing. for in tending to so close the springwould wedge the shoulders of thelinks againstthe sides of the button 11and the whole would remain in placeiVhen it is desired to dismount thefelly for tire or other repairs, it is only necessary to operate the keyin a reverse manner to thatreferred to above, so as to bring the springand its connecting-links back into the position shown in Fig. 4, and assoon as the links are moved beyond the dead-point of the position inwhich they are in a straight line the movement continues automaticallyunder the action of the spring. The head of the button 1 is preferablyprovided with a washer or small disk of leather or indie-rubber Q, whichwill completely close the aperture j in the housing (7 during use forpreventing dust or mud from penetrating to said housing.

in the second form of construction (shown The spring-ring now completelyfills 4 in Figs. 6 and '7) the spring tends to expand,

and its position of rest will correspond to the.

during the taking apart and putting together I again of the felly orrim. After the reassembling the hooked end of the plate 7* is disengagedfrom the button if, the spring on relaxing then causing theconnecting-links to rise again and he flat against the interior of j theupper groove, thus connecting the two parts of the telly together again.With this form of construction if one of the pivot-pins of theconnecting-links should break the spring tends to forcibly connectthetwo members of the felly, so that no accidents need be feared.

For preventing circumferential displacement of the member-t with regardto member 64 pins :0 with countersunk heads may be fixed in the saidmember a, adapted to engage corresponding recessesin the inner edge ofthe member 6. (See Fi s. 3 and 5.)

The tire may be fixed and held on or felly by any known means.

Fig. 8 shows a form of felly somewhat different from that shown in theother figures, the part b being formed by a east-iron sheet suitablybent to form its part of the housing.

The member d mayextend across the whole Width of the member a or acrossonly part of said Width, according to requirements.

The improved dismountable felly described can obviously be used withwooden or metal wheels. p

The connecting-links and pull or push button might also be replaced by acam or eccentric or any other means by which the ends of the spring maybe brought nearer to or -forced away from each other, and the springringmay have a constant section throughout or a'varying section, so as tofacilitate its perfect circumferential adaptation to the interior wallof the housing.

'Having now descri bed'my invention, what I claim as new, and desire tosecure by Letters Patent, is-=.-

1. A dismountable wheel. rim or folly comthe rim pose set forth.

2. A dismountable wheel rim or felly comprising 1n combination twocircular rigid continuous members a and 7) fitted one upon the other, anannular groove formed respectively on each member so that by the fittingof both members an annular housing 0 is provided, a non-continuousspring-ring (Z inserted in the annular housing 0 and tending to coil orclose itself, a pulling or pushing member 11, connecting-linksf and rhaving one end pivoted respectively to each of the free ends of thespring-ring I] and the other end pivoted together and to the member 1',and holes 7: andu provided respectively in the member I and in a fixedpart of the felly in order to receive the tenons of a manipulating-key,substantially as and for the purpose set forth.

3. A dismountable wheel rim or folly comprising in combinatior twocircular rigid continuous members a an I; fitted one upon the other, anannular groove formed respectively on each member so that by the fittingof both members an annular he ising c is provided, a non-continuousspring-ring inserted in the annular housing 0 and tending" to openitself, a pulling or pushing member '1. provided with a recess,connecting-links f and having one end pivoted respectively to each ofthe free ends of the spring (I and the other end pivoted together and tothe membe v'ste r fixed to the wheel and provided with a ok adapted toengage the recess of the member in the unmounted position, and holes :1)and o pro vided respectively in the member 0' and in a fixed part of thefelly in order to receive the tenons of'a manipulating-key,substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
